REFRIGERATNG UNIT Filed NOV. 8, 1928 R m n m Patented 'July 7, 1931 UNITED STATES PATENT OFFICE LE'W'IS W'. EGGLESTON, OF DETROIT, MICHIGAN, ASSIG-NOR T0 AMERICAN RADIATOR COMPANY, 0F NEW YORK, N. Y., A CORPORATION 0F NEW JERSEY BEFRIGERATING UNIT vAl'npleation -led November My invention relates to improvements in apparatus for refrigerating, cooling or the like, andthe same has for its object more particularly to provide a simple, reliable and eficient apparatus which is extremely compact in form, inexpensive to produce and economical in operation. n

Further, said invention has for its object to provide a refrigerating element in which the refrigerating agent Will be more uniformly distributed and circulated throughout the element. Further, said invention has for its object a refrigerating element or section having a float-chamber arranged at the top thereof coextensive in length with the length of said section and communicating with the body portion of said section at a plurality of points 1n its length. y

Further, said invention has for its object to provide a refrigerating element or sectlon having a series of vertical passages therein, and having a float-chamber, which contains the automatic control for the refrigerating agent, disposed along the upper longitudinal -edge of the element or section and communieating at a plurality of points throughout its lengt severally with said passages in order to insure the uniform and efective distribution and circulation of the refrigerating agent in and through the element or section.

Further, said invention has for its object to provide a compact refrigerating element or section with its float chamber disposed longitudinally along the upper edge thereof and formed integrally therewith.

Other objects and advantages will in be obvious and in inafter.

-To the attainment of the aforesaid objects and ends my invention consists in the novel par# part be pointed out heredetails of construction, and in the combination, connection and arrangement of parts hereinafter more fully described and then pointed outl in the claims. y

In the accompanying drawings forming part of this specification- Figure 1 is a face view showing one form --refrigerat'in'g element or section con- 8, 1928. Serial No. 317,948.

structed according to, and embodying my said invention;

Fig. 2 is an end view thereof;

Fig. 3 is a plain or top view;

Fig. 4 is a vertical section on the line 4--4 ig. 1, and

Fig. 5 is a detail longitudinal section on the line 5 5 of Fig. 1.

In said drawings 10 designates a refrigerating element or section preferably formed as a cast metal unit comprising a rectangular panel or. 4body portion 11 provided with a series of verticahparallel tubular portions 12 separated 'by 'ntervening webs 12EL and forming passages communicating `at their lower ends with a transverse header 13, and at their tops withY a tubular, .longitudinal float-chamber 14, substantially co-extensive in length with the length of said section, and provided at its base with openings communieating severally with the upper ends of the vertical passages in the tubular portions 12. The float-chamber 14 is open at one end and provided with a iianged portion 15 adapted to recei-ve a cover-plate 16 having a coupling 17 at its outer end for connection with a source of refrigerating agent, and at its inner end with a suitable valve, as 18, controlled by a pivotally mounted float 19 for automatically controlling the admission ofthe'refrigerating agent to the interior of the floatchamber and the bodyportion 11 of the element or section 10. The outer side of the float chamber 14 is provided with a series of spaced transverseribs 20, serving as extended surface, and adjacent to its opposite ends said float-chamber is provided with bosses 21 to engage with correspondingly located bosses on a cooperatlng refrigerating element or section when a number thereof are assembled. The lower transverse header 13 is provided on its under side adjacent to its ends with 'threaded apertures 13 to receive the ends of ow 4or return pipes, sembling of a number of el vertically in end to end relation, and the float-chamber 14 is provided in its upper f side with a threaded aperture 14*i to serve as an outlet under certain conditions .of use.

The panelyor body portion 11 is provided ements or sections or to permit of the as-l on one of its side walls with a series of vertical ribs 22 which merge at their upper ends with the transverse ribs 2O on the outer side of the lioat-chamber, and upon its opposite side the panel or body portion 11 is provided with a plurality of horizontal ribs 23, which in cooperation with correspondingly located ribs of `an adjacent element or section or With other cooperating means, Will constitute supports for the objects to be cooled.

The operation of the apparatus Will be largely obvious. It need merely be noted that in operation the refrigerating fluid may, or example, be admitted to the element or section by Way of the float-chamber 14 under control of the valve 18 and float 19. And that by disposing the loat-chamber 14: horizontally, and having coextensive in length With the length of the section it becomespossible to establish communication severally with the upper ends of the vertical passages 12 in the panel or body portion 11, and thereby effect the immediate and uniform distribution of the refrigerating agent, and insure the rapid and uniform coolin of the element or section as a Whole.

aving thus described my said invention,

what I claim and desire to secure by Letters Patent is:

A refrigerating unit formed as an integral casting comprising a body portion including a series of flat tubular portions arranged side by side in spaced relation, a header at one end of said body portion common to the lower ends of said tubular portions, a ioat-chamber at the opposite end of said body lportion having openings therein communicating severally with said tubular portions, and a series of transverse ribs arranged in spaced relation and extending laterally from one side Wall of said body portion intermediate said float-chamber and said header, and vertical ribs arranged in spaced relation and extendv ing' from the opposite side Wall of said body portion, substantially as specified.
